My first encounter with LEDs was for a school project where I wanted to use one as a little red indicator. In those days, they were simply Light-Emitting Diodes, nothing more. The though that they would, one day, be used as a source of light didn’t even remotely cross my mind.

In the last few years, however, LED technology has taken giant strides and the early problems like inaccurate colour rendition and a limited light-cone have been, to a great extent, sorted out. Added to that, the costs–which used to be very high–have come down to relatively affordable levels. While they are not, still, competitive with fluorescent lights, the day is probably not far when LEDs will replace them. Even at today’s prices, they are already more economical in the long term.

With their small size and favourable physical properties—they run cool, have a long life and are able to vary their colour—LEDs have made it possible for lighting designers to come up with some very original creations.

The price of electricity in India has gone up substantially of late and the argument for eliminating incandescent bulbs has become even stronger. Scroll towards the bottom of this article to see cost comparisons for Bulbs, CFLs and Fluorescent Tubes.
